Buu at this point was way above SSJ3, GOku even said please to Buu to let him and Gohan fuse, SSJ3 was nothing to him, how do I know, Gohan was more powerful than Goku, Goku was SSJ3, Gohan was no match for SuperBuu, Thats w/o Gohan absorbed!!!

More detailed sure, as Japanese animators aren't as lazy as Western ones. It's a matter of opinion about the rest though.

yes a matter of opinion, but then again Look at Superman's legs, skinnier than shit. loloverall yes, both are aimed towards kids, I was just a kid that preferred DBZ, but I like the X-Men show 1990's version a lot more than any DC show.and I like the drawings of the Silver Surfer show much more as well.

DC has great art, just not the shows lol, and DBZ is not too focused on costumes and capes, or tights another added bonus.
